Titanium alloy rau tsheb kauj vab
Titanium tsheb kauj vabNws muaj qhov zoo ntawm qhov hnyav, siab zog, zoo corrosion kuj, thiab qaug zog kuj. Txij li thaum nruab nrab -1980s, titanium tsheb kauj vab tau tsim, uas tau txhawb nqa kev siv cov khoom siv titanium. Piv txwv li, ANCOTECH thiab HAYNES INTERNATIONAL, peb lub tuam txhab tsim Ti3Al-2.5V kav hauv Tebchaws Meskas, Thiab SANDVIK SPECIAL METALS tau tig mus rau kev lag luam tsheb kauj vab.
Ti-3Al-2.5V thiab Ti-6Al-4V yog cov feem ntau siv titanium alloys rau tsheb kauj vab thav duab hauv kev xaiv cov khoom siv. Piv nrog rau lwm cov titanium alloys, Ti-3Al-2.5V muaj qhov zoo tshaj plaws ntawm cov khoom muaj zog, cov txheej txheem zoo plasticity, thiab kev ua haujlwm vuam zoo, tab sis nws qhov tsis zoo yog tus nqi siab. Txawm hais tias nws yog tsim rau aircraft hydraulic systems, nws ua tau raws li qhov yuav tsum tau ntawm lub lag luam tsheb kauj vab rau cov khoom siv vim nws cov formability zoo, corrosion kuj, elongation, siab qaug zog, thiab tsawg ntom.
Ob peb xyoos dhau los, cov ncej ua los ntawm kev lag luam ntshiab titanium caj npab thiab tsis-aviation Ti-3Al-2.5V (qib kis las) titanium alloy yog nrov heev. Ti-6AL-4V yog cov khoom siv titanium alloy uas paub tab tshaj plaws nrog cov khoom siv kho tshuab zoo thiab cov ntaub ntawv ua tiav tshaj plaws. Nws muaj cov txheej txheem zoo plasticity thiab superplasticity, thiab tsim nyog rau ntau yam kev ua haujlwm siab thiab sib sau. Nws kuj tseem tuaj yeem raug welded thiab machined nyob rau hauv ntau txoj kev, tab sis nws formability, weldability, thiab machinability yog inferior rau yav dhau los.Ti-6Al-4V kuj yog qhov txaus nyiam rau kev ua thav duab. Nws modulus thiab lub zog yog me ntsis siab dua Ti-3AL-2.5V, tab sis nws yog ib qho nyuaj rau ua nws mus rau hauv ib tug me me-inch tsheb kauj vab ncej yeeb nkab. Lub crankshaft positioner, pedal, handlebar, thiab lwm yam tsheb kauj vab txuas nrog tus ncej feem ntau yog ua los ntawm Ti-6Al-4V.
Vim tias cov nqi smelting siab ntawm titanium alloy thiab cov ntsiab lus siab ntawm molybdenum, vanadium, chromium, niobium, thiab lwm yam khoom kim heev, tus nqi khoom yog nyob rau sab siab; Tsis tas li ntawd, vim muaj cov khoom siv tshuaj lom neeg ntawm titanium alloy, cov yas tsim xws li extrusion, dabtsi yog khoov thiab vuam yog yooj yim rau nqus hydrogen thiab oxygen, uas degrades cov khoom ua tau zoo, thiab cov formability, weldability, thiab machining kev ua tau zoo kuj tsis zoo, uas zoo heev ua rau cov txheej txheem nqi, uas txwv tsis pub muaj koob meej ntawm titanium alloy ncej. Tam sim no qee cov khoom lag luam txawv teb chaws tau cog lus los tsim cov ntaub ntawv tshiab titanium alloy nrog tus nqi qis thiab ua haujlwm yooj yim.
Titanium alloy rau kev sib tw ( tsheb / maus taus)
Titanium yog cov khoom siv zoo tshaj plaws rau cov khoom siv hauv tsheb. Kev sib txuas rods, li qub, silencers, tso cov kav dej, hubs, thiab lwm yam khoom tsim nyog rau kev tsim khoom nrog titanium alloys. Piv txwv li, cov pa tawm ntawm Coryete Z06 qauv tsim los ntawm General Motors Corporation ntawm Tebchaws Meskas siv cov titanium silencers, Lupo FSI qauv ntawm Volkswagen ntawm lub teb chaws Yelemees siv titanium springs, thiab titanium noj ntawm Japanese tsheb tau mus txog theem ntawm 200 ~ 300t. /a.Nyob rau hauv yav dhau los, 60 lab lub tsheb tau tsim txhua xyoo hauv ntiaj teb. Yog tias 50 feem pua ntawm cov tsheb siv 1kg ntawm cov khoom siv titanium txhua, qhov kev thov rau cov khoom siv titanium hauv ntiaj teb yuav nce ntau dua 60 feem pua. Thaum ntxov li 20 xyoo dhau los, kev sib tw cav tau txo qhov hnyav ntawm titanium li qub thiab titanium txuas rods.
Raws li tus pas txuas txuas ntawm lub cav sib tw yog ib qho kev thauj khoom uas muaj kev cuam tshuam muaj zog thiab muaj zog dynamic kev nyuaj siab, nws lub teeb yuag tuaj yeem txo lub zog thiab lub zog tso zis, txhim kho qhov cuam tshuam ntawm dynamic tshuav, thiab txo cov suab nrov, kev co, thiab roj noj. Ntxiv nrog rau cov txheej txheem kub forging feem ntau, titanium alloy txuas pas nrig ua los ntawm cov hmoov hlau metallurgy (forging) yog cov cuab yeej siv siab tshaj plaws nrog cov khoom siv siab, kev ua haujlwm zoo, kev ua haujlwm huv, thiab kev sib txuas ntawm cov pas nrig zoo. Tam sim no, hmoov forging tshuab ntawm kev sib txuas rods txawv teb chaws tau paub tab. Nyob rau hauv 1995, cov hmoov-forged txuas rods ntawm Jaguar cav AJ-8V tsim los ntawm Bridgefoot Cav Hoobkas nyob rau hauv lub UK tsuas yog 605g nyob rau hauv zoo Piv nrog rau zoo tib yam tuag forgings, cov khoom siv piv tau nce los ntawm 48.3 feem pua rau 95.9 feem pua.
